A New Cast Stone Roller Kiln and its Combustion Control Approach

Abstract:

The domestic cast stone industrial production is of high energy consumption and low productivity, so a new cast stone roller kiln is firstly developed. A combustion control approach is advanced to accommodate the new roller kiln architecture and meet the combustion control requirements. Continuous proportion and pulse control methods are adopted to the high-speed isothermal burners with internal dense distribution. Two controllers mutually collaborated in pairs to obtain the internal uniform temperature. The implementation of the combustion control scheme is put forward. The application results demonstrated that the new roller kiln and combustion controller could effectively decrease the furnace temperature difference, increase stability of the combustion atmosphere, improve product quality, reduce energy consumption and NOx emissions.
